BINDING-ROLLER MACHINE,

Application filed September 15,1921.

a citizen of the United States, and a resi- Vdent of Watertowm in the county of Mido dieser: and State of Massachusetts, have invented certain new and useful Improvements in Binding-Roller Machines, of which the following is a specification.

My invention relates to a machine or apparatus designed to roll down and press into firm and smooth adherence the binding strips or foxing commonly applied at or to the edges of the soles of rubber footwear.

The present invention aims to provide a i5 simple, durable and eicient machine by which such action may be much more expeditiously. performed with a resulting increased uniformity in product and with a material saving in labor costs.

The invention'inciudes the novel features of construction and arrangement and combination of parts hereinafter described and particularly defined by the appended claims.

An embodiment of my invention is illustrated in the accompanying drawings, in

which- 4 Figure 1 is a side elevation.

F ig. 2 is an end view.

Fig. `3 is a section on line 3 3 of Fig. l;

Figs. a and 5 are detail views of the last support adjusting means.

Figs. 6 and 7 are detail views of the in.

.clined arm controlling connections.

The machine is shown in the drawings as preferably arranged in duplex form so as to be capable of operating upon two shoes, the elements being so arranged and timed that the shoes or other articles of footwear may be removed and replaced alternately.

Referring by reference characters to this drawing,v 1 and 1a designate lasts upon which the footwear is to be supported during the rolling operation, and as the supporting and cooperating mechanism'for both are the same, a description in the singular will suHce. Eachlast is mounted on or .Y carried by a support 2 through the intermediary of a heel support 3 and a toe support 4, the heel support having a projection 3a designed to engage a recess in the last.

The heel support 3 is slidably carried by a vertically adjustable member 5 which has aguideway therein by which the member' 3 is guided in its reciprocating movement andthe member or support 3 is adapted to be Serial', No. 500,846.

moved towards and from the toe-support by suitable means such as a screw-threaded rod 6 engaging a threaded opening through Athe support 3,*theV screw being journaled in suitable bearings'provided onV the member 5 and having a non-circular head 6a by which it may be turned. .In a similar manner the toe support 4 is slidably carried by the support .2 through the provision of a suitable guideway and an operating screw 7, having a gear connection 7 a with screw 6, these adjustments being designedto accommodate varying sizes of lasts. The last Supporting member 5 is vertically adjustable to provide for variations in the heights of lasts, such vertical adjustment-being conveniently secured by providing the'member 5 with a depending bar or rod 5a which is provided with a rack a meshing with a gear carried by the shaft of a suitable operating wheel 8. Associated with the last is presser means preferably in the form of a pair ofvpresser rollers 9 and 10 whichare designed to press upon and roll down the binding strip or foxing in `the manner hereinafter described, the roller 9 when in engagement with the foxing lying in a substantially vertical position or perpendicular to the sole of the last and the roller 10 in an inclined position (preferably at an angle of approximately 450).-

Whilethe presser rollers are thus held in Contact with the foXing, relative 4movement of the roller-carrying means and the last-support'is .effected whereby the rollers 9`and lO are caused to roll completely around the edge of the Sole preferably first in one direction and then in another so as to applythefo'Xing firmly and smoothly to the shoe edge. In my preferred embodiment of the invention, this movement 'is accomplished by. mounting the support '2 uponavertical shaft 11. journaled in the base frame 12,

-upon which shaft are provided upper and lower beveled gears 13 and 14 which are loose on the shaft and which meshwith a beveled gear 15 carried by a driving shaft 16 which may be driven in any suitable manner from any desired source of power, as for instance by a sprocket cham (not shown) f passing around the sprocket wheel17. The

gears 13 and 14 have reversely placed clutch faces or members 13a and 14a which are designed to be alternately engaged by coacting clutch faces 18l and 18". These clutch faces 18a and 18b are carried by a vSleeve 18 splined on the shaft, Vwhich sleeve is encircled by a collar member 19 within which collar the sleeve is rotatably mounted but with which it hasV suitable annular flange engagement so that endwise movement of the collar will produce corresponding movement of the sleeve and clutch faces. I

The Vcollar is provided with a cross head 19a which is connected by springs 2O with the base frame, which springs supplement the actionof gravity and tend vto hold the i parts in such position as to clutch the lower gear 14 to the shaft 11.l Shaft 16 carriesa camv21 which is designed to coact vwitha suitable contact portionc'arried by the collar, the cam having such a contour that during a certain portion of its movement` it will raise the collar and sleeve to unclutch the gear 14 from the shaft and clutch the gear 13, whereby the shaft 11 will be rotated in one direction while during the remaining portion of the cam the parts will be lowered to unclutch the gear 13 and clutch the gear along the shaft against the pressure of thev centralizing springs 23 and 24. Shaft or arm 10a is articulated at 10b to a Support 25 and has fast thereon a plate or bracket member 10C provided with an arcuate slot c whichV is engaged by a transverse pin 26a carried by a pull rod 26, the pin and slot constitutinga lost motion connection. YPull rod 26 is connected at 26" Vto the one arm of a bell crank lever 27 fulcrumed on the base frame andV having its other arm provided with a roller 27a designed to coact with a cam 28 fast on shaft 16. The roller carrying arm of bell crank lever 27 is connected by a link 29 and pin and slot or lost rmotion connection c2 Vwith an arm 9C of the shaft 9b on whichlever 9a pivotsA so that when .bell crank lever 27 is rocked by thehigh part of l cam 28,l lever 9El will be swung'o'n its pivot to remove the roll 9 from the shoe at the same time'that the pull rod 26 Visactuated to remove the roll `10 from the shoe, such removed positions being shown on the right of Fig. 1. A' spring 30 connected to arm 9d tends to rock the arm 9a so as 'to bring the roll 9 into contact with `the shoe anda spring 31 through flexible band 31a passing over guide roller 31b tends to rockthe arm 10a onV its pivot 10b1 to bring the roll 10 into contact with the shoe, such contacting position being shown at the left of Fig. 1, at which Vthe last and having their axes re time the roller 27a coincideswiththe lo part of the cam 28. Each sprocket or driving member. 17 is preferably arranged to be controlled by a machinestop mechanism of any approved type, indicated conventionally at '32 and controlled by foot lever 33 and so arranged that by pressing upon the lever 32 the corresponding roller mechanism will operate Y through a complete cycle and be automatically ,stopped-at the completion, suchstop being so timed that the high part ofthe cam i y 28 will be in contact with roller 27 P and the parts shown in the position-shown in 1, y

allowing removal ofthe last carrying the linished shoe and its replacement by a 4fresh last. f

During this timel the companion parts` V will be in operation as indicated on the left in Fig. 1.V

' Assuch machine stop mechanisms are well Y known and form rper se no part of the present invention, conventional Aillustration thereof is deemed sufficient.
